I'm not sure if any of those seem all that interesting. Maybe the Nidoran?
Another possibility: You're the same person that traded me a slew of Subway items for a copy of my Terrakion, correct? I could use some more items if you want to just offer that instead:
Life Orb (the one you gave me was being held on a pokemon that I accidentally released, whoops!)
Choice Specs
The EV training items for: HP, Def, SpD, Atk (I have the SpA and Speed items)
A freaking Water Gem, if you have one, since I can't seem to find one.
Any of the decent type resist berries (Chople, Coba, Haban, Yache, Occa, Charti, whatever)
Let me know what you've got available. :)
